The dual-membrane watermelon interplanting peanut planting model not only guarantees the watermelon market in the morning, but also obtains high benefits, and increases the peanut production. This model produces about 4,500 kilograms of watermelon per 667 square meters, about 360 kilograms of peanuts, and 4,000 square meters of output value per 667 square meters under fine-grained conditions. It is a high-yield, high-efficiency planting model. Planting specifications are selected every 2 meters as a planting belt, watermelon plant spacing is 40 cm, 800 plants per 667 square meters, 7 rows of peanuts are planted within each planting belt, row spacing is 3520 cm, and 9500 piers are planted per 667 square meters. about. Soil Preparation and Fertilization To create a soil environment that is loose, air-permeable, insulative and water-reserving, and suitable for the growth and development of watermelon roots, the melon fields must be ploughed. Each 667 square meters of high-quality ring fertilizer is 4500-5000 kg, 50 kg of nitrogen fertilizer, 75 kg of phosphate fertilizer, and 15 kg of potassium fertilizer. 1 kg of zinc fertilizer is used as base fertilizer. Cultivation of watermelon varieties should use precocious Admiralty Guanlong, in early February in the greenhouse with nutritious germanium seedlings, seedlings, appropriate control of soil moisture, to prevent the formation of "high-legged seedlings." At the same time, properly control the temperature in the greenhouse, pay attention to ventilation, to prevent the formation of "small old seedlings." Planting began when the seedlings grew to "3 leaves and 1 heart". Colonization should be carried out in sunny and windy weather. The suitable time is from 10 a.m. to 4 p.m. After the seedlings were planted, they were covered with a layer of plastic film (film width 35 to 40 cm), and then covered with a small arch shed (arch 50~55 cm wide). When the plant enters the extension period, the small arch shed is removed and the double vine pruning is performed. The main vine and the second female flower are left to leave the melon, leaving 1 melon per plant. In the 5 leaf stage, 10 kg of diammonium phosphate is chased every 667 m2, and the swelled melons are combined with swelled melon water. Each 667 m2 chases urea and potassium sulfate by 10 kg each. Care must be taken to control weeds and pests throughout the growing season. Cultivation of peanuts In mid-May, combined with pouring watermelon water, interplanting peanuts. Immediately after the harvest, the watermelons were extirpated and loosened, and the plants were cleared of grass. To promote early-onset seedlings, water can be combined with 25 kg of nitrogen, phosphorus, and potassium fertilizer per 667 square meters. In the middle term, we must pay attention to extermination of grasses, carry out soil cultivation before mulching, and promote the results of fruit needles. In order to prevent peanuts from “two insects and one diseaseâ€, 1.5 to 2 kg of phoxim granules can be used per 667 square meters, and they are sprinkled in the rows during the seedling stage, and then spread to the ground. In the middle and late period, the disease was cured with chlorothalonil or carbendazim spray. The timely control of apprentice trends. In the next needle period, every milliliter of 667 square meters is made up of 20 milliliters of melatonin, 50 kilograms of water, and 2 shots.
